用血管铸型法,动一静脉连续灌注法、组织化学DAB法和生物体视学方法研究大鼠海马的血管构筑,结果表明:大鼠海马由大脑后动脉的分支——海马纵动脉供血,后者发出数支耙状分支进入海马,根据分支分布部位可分为海马内,外侧横动脉,它们经逐级分支移行为毛细血管,供应海马各区及齿状回.海马内毛细血管的分布具有与海马皮质分层相对应的层次性.海马各区及齿状回毛细血管的长度密度为齿状回 >CA_3>CA_4>CA_2>CA_1.海马具有内侧及外侧两个静脉系统.本文对海马的血管构筑及其缺血敏感性和选择性损伤进行了讨论.
The vascular architecture of rat hippocampus was studied by means of vascular casting, continuous perfusion of a vein, histochemical DAB and biopsy. The results showed that the hippocampus of rats were fed with the hippocampal longitudinal artery, the branch of the posterior cerebral artery, The latter issued a few rake-like branches into the hippocampus, according to the distribution of branches can be divided into lateral hippocampus, lateral transverse artery, which by graded branch of the capillaries, the hippocampus supply all regions and dentate gyrus hippocampal capillary distribution with And hippocampal cortical stratification corresponding to the level of the hippocampus and dentate gyrus capillary length density of the dentate gyrus> CA_3> CA_4> CA_2> CA_1.The hippocampus has a medial and lateral venous system.In this paper, the hippocampal blood vessels Construction and its ischemic sensitivity and selective damage were discussed.
